PLEASE NOTE.

Revised global historic fossil-fuel CO2 emissions estimates are now
available from CDIAC at ftp://cdiac.ornl.gov/pub/ndp030/. The revised
pre-1950 estimates are based on energy production and trade (imports and
exports) data rather than production data only, and extend back to 1751.
These revised emissions estimates (Marland et al. and Boden et al.)
agree well with these emissions estimates over comparable time periods
but users are encouraged to access the newer data. There are no plans
to ever produce any updates to NDP006.
